JNDI连接不到数据源实例？
main net.sf.hibernate.connection.DatasourceConnectionProvider -[FATAL] -Could not find datasource: java:comp/env/jdbc/sysuser
javax.naming.NamingException: Cannot create resource instance

这是我hibernate中的部分配置：
<session-factory>
<property name="hibernate.jdbc.batch_size">5</property>
<property name="connection.datasource">java:comp/env/jdbc/sysuser</property>
<property name="testConnectionOnCheckin">true</property>
  <property name="idleConnectionTestPeriod">60</property>
这是TOMCAT中的配置conf>localhost：
